Power connectors
At first, connect the screw, labelled with "GND" to Ground (e.g. to the 19"-Rack the chassis is mounted in).
After that connect the chassis to 90-240V A/C via IEC connectors. Use power cords with an earthing contact and protective earth connection only! The sat-nms LFTX/RX is working with only one connected power supply as well, but we strongly recommend to use two different power supplies to ensure the maximum system availability. In case of one power supply breaking down, the system will still be working without interrupt.
Power supplies
If your LFTX/RX frame is equipped with hot-swap power supply option, the power supplies can be changed during the sat-nms LFTX/RX frame is in operation. To change a power supply, always disconnect the mains of the power supply that has to be changed and wait at least 10s (for internal discharge). Open the 2 screws with which the power supply is mounted an pull the power supply, using the attached handle bar, out of the unit.
To put in a power supply, you have to do the same things in reverse chronology: Put the power supply into the slide rails, until the front plate contacts the mounting rail. After that fix the power supply with the provided screws to ensure a proper contacting of the connectors on the power supply with the connectors on the backplane.
ATTENTION: To avoid the possibility of an electrical shock, never handle with a power supply that is connected to mains!
